You have 2 sound barriers instead of 1. Guess I got lucky, did it just like the guy in the video, it was very simple and easy to do. The Comtronics died of old age, am currently using a Gulf Coast Avionics noise canceling headset, and it is doing a good job - wonder what would happen if you attached the earbud speakers to the GCA headset speakers w/ their noise canceling function? Better? Worse? -------- Richard Pike Kolb MKIII N420P (420ldPoops) Kingsport, TN 3TN0 "Living for your own pleasure is the least pleasurable thing a man can do.

Advancing the pilot side throttle pulls the passenger side throttle lever open, while also pulling the carburetor cable slide up, and when you retard the throttle, it also pulls the passenger side throttle closed and lets the carburetor cable slide down. You do that by making the cable attach points and pivots 180 degrees out at the same pivot and attach lengths for the two different throttle levers. Crude drawing attached, the big loop is the cable inside the secured cable sheaths. You'll get the idea. You will need cable sheath attach points on your fuselage structure to anchor the cable sheaths into, and also cable adjusters in each half of the loop to get things adjusted. You will want the system to have no slop, yet not bind. It's not hard, but the devil is in the details of trying to get it to work smooth. I still had the old parts out in the hangar, it is not possible to assemble them to show the system, but here is some of the hardware I used. -------- Richard Pike Kolb MKIII N420P (420ldPoops) Kingsport, TN 3TN0 "Living for your own pleasure is the least pleasurable thing a man can do.

The Halo actually has the speaker elements mounted on the headband, with small tubing connecting to the ear plugs. I would have thought that the Clarity Aloft would be even quieter. Are you sure you had a good seal between the ear plugs and your ear canal? If they don't seal up completely just like regular noise blocking ear plugs, then they won't block external sound very well at all. I've flown with earplug style in-ear phones (Sony in-ear monitors designed for musicians) under Lightspeed active noise cancelling headsets, and it is a bit quieter with a noise cancelling headset on top, but at the expense of wearing the headset. One of the things I love about the Halo is that I don't have the weight/heat of the bulky headset on my head. I've never tried any type of in-ear active noise cancelling headset, but if you could rig one with a mic, that sounds like the ultimate solution for those of us who can tolerate 'earplugs' in our ear canals. For those who have never used any of this stuff: There's a huge difference between 'earbuds' like what came with your iphone and earplug style systems like the Halo and Clarity Aloft. Regular earbuds do not seal to the ear canal, so they don't really block much sound at all. All regular earbuds will get you is louder sound (and quicker hearing loss).

Using a "pencil solder gun" I had no problem at all with soldering the wires? to the speaker. Perhaps it was the type of flux core solder that I had. I also bought the QT Halo headset, and I liked it for the most part. I had no problem hearing the radio, in fact I had to turn it down quite a bit, and the best part is that I could listen to my music while flying. Not very satisfying with a normal headset. I however was not a fan of the mic. I put an Oregon Areo mic cover on it and it helped a lot, but the "boom for the mic was as limp as 30 day old celery. I finally taped it to some alum wire to give it a bit of a spine. Other wise I had to hold it in front of my mouth if I wanted to talk to some one. My cockpit is just a cover (factory wrap around) over the area that I sit. If I turned my head it would crack the squelch and I would get a shot of full motor noise. So it was necessary to turn up the squelch a lot to keep it from cracking. You asked about seal, and I did have a good seal, but you also pick up ambient noise through the bones that surround your ear as well. While I could hear great, I felt that the noise of that HKS was still too loud. I was considering using a set of ear muffs to help with the noise. To be clear- I never had any problem with hearing the radio or my music. My wife however often mentioned the motor noise was quite loud, and there was occasional static. ( I think that there are better mic's out there than the one that they use.) I have a base station here at the house so I can talk with the wife to get her input on clarity on her end of the conversation. I decided to try adding the ear buds to my Sig S45's. I have found them to be the best option for me even over ANR headsets. ( The ANR is set for GA and works best on the 2400 RPM's of those engines. Ours turning 6000 RPM, are out of the range that they generally work best at.) However wearing glasses I was not happy with the noise even with gel ear seals on the S 45's. I felt that I had to turn the sounds that I wanted to hear up to the point that my old experienced ears would be still getting damaging noise levels. I could not hear my music very well and if I played it as loud as I needed to hear it at all in the plane, it would cause me to wince at that level out of the plane. After completing the modification I rolled the plane out for some touch and go's. I plugged the ear buds in, covered my ears with the headset, and found that I had to turn the volume down on both the headset and the music radio for the first time. The noise level was substantially reduced from both the Halo set and the S45 before modification, with the ear buds. Upon landing my wife also confirmed that on her end the transmissions were a lot clearer, louder and without static. I will be using my Halo set as a backup. There was that much improvement.

Noise is extremely fatiguing. BTW: No cockpit noise comparison between a Kolb and an RV4. Kolb is much, much louder and of a much higher frequency, engine and prop. Pushers are normally much louder inside as well as outside the cockpit.

He's 'local' for me, and I bought mine by walking into his office. Nice guy & would probably work with you on the issues. I haven't used mine in an open cockpit, so don't know about whether wind would affect boom position (but suspect that it should remove it from your head before it actually bends the boom, assuming that it isn't defective). No experience with open cockpit wind noise on the mic either (except getting it in the flow of the cockpit vent, which triggers *any* mic), but I have heard of some people getting the boom on backward & talking into the noise cancelling port instead of the front of the mic. Might be worth a check. Also, if the port gets clogged with debris it will kill the noise cancelling function of the mic. Agree that active noise cancelling doesn't do that much in open cockpit; most of the problem is wind noise, which is *much* higher frequency than even a 2 stroke. That's where good physical seal and a bit of mass really help. John, Are you talking about iphone/mp3 player type buds that basically hang in your ear? If so, be aware that using those inside a set of regular headphones will not reduce noise much if any over the headphones alone. Yes, you will likely be able to hear better than with headphones alone (for a short time), but all you're doing is making the volume of the radio reception louder, which is *adding* to the ear's total noise exposure. Any of us who have flown for a number of years, and/or abused our ears in other ways (I did concert sound work in one of my previous lives) need to not just hear today's radio comm, but keep whatever hearing we have left. :-) There are in-ear models that actually 'plug' your ear just like industrial earplugs (not as cheap), or you can have custom molded inserts made, (not cheap at all). What's your remaining hearing worth? As to noise levels in RVs vs Kolbs, I can't compare. But I have flown in the back seat of an Aircam with two 912s. Didn't seem that bad at the time, but maybe the 912s were cancelling each other. Or I was having too much fun to notice the noise...

Prop and engine noise is magnified and confined to the enclosed cockpit. Open cockpit is not as loud. Wouldn't do me much good to hand an ear bud on my ear. I've been wearing hearing aids since 1978, while still on active duty and drawing flight pay. Larry shot me a bc to get good ear buds that actually seal the ear canal. The DC H-13.4 do about as good a job as any passively. The additional passive noise reduction of the ear buds should allow for me to hear with lower radio/intercom volume. john h mkIII Titus, Alabama From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of Charlie England Sent: Tuesday, March 10, 2015 7:36 PM Subject: Re: Kolb-List: Headset Modification Larry, Might be worth a call to QT. He's 'local' for me, and I bought mine by walking into his office. Nice guy & would probably work with you on the issues. I haven't used mine in an open cockpit, so don't know about whether wind would affect boom position (but suspect that it should remove it from your head before it actually bends the boom, assuming that it isn't defective). No experience with open cockpit wind noise on the mic either (except getting it in the flow of the cockpit vent, which triggers *any* mic), but I have heard of some people getting the boom on backward & talking into the noise cancelling port instead of the front of the mic. Might be worth a check. Also, if the port gets clogged with debris it will kill the noise cancelling function of the mic. Agree that active noise cancelling doesn't do that much in open cockpit; most of the problem is wind noise, which is *much* higher frequency than even a 2 stroke. That's where good physical seal and a bit of mass really help. John, Are you talking about iphone/mp3 player type buds that basically hang in your ear? If so, be aware that using those inside a set of regular headphones will not reduce noise much if any over the headphones alone. Yes, you will likely be able to hear better than with headphones alone (for a short time), but all you're doing is making the volume of the radio reception louder, which is *adding* to the ear's total noise exposure. Any of us who have flown for a number of years, and/or abused our ears in other ways (I did concert sound work in one of my previous lives) need to not just hear today's radio comm, but keep whatever hearing we have left. :-) There are in-ear models that actually 'plug' your ear just like industrial earplugs (not as cheap), or you can have custom molded inserts made, (not cheap at all). What's your remaining hearing worth? As to noise levels in RVs vs Kolbs, I can't compare. But I have flown in the back seat of an Aircam with two 912s. Didn't seem that bad at the time, but maybe the 912s were cancelling each other. Or I was having too much fun to notice the noise...

Are you sure you had a good seal between the ear plugs and your ear canal? ---------------------------------------------------------------------------- -------------------------------------------- I just finished modifying my Sig S45 headset with a set of "ear buds". Using a "pencil solder gun" I had no problem at all with soldering the wires? to the speaker. Perhaps it was the type of flux core solder that I had. I also bought the QT Halo headset, and I liked it for the most part. I had no problem hearing the radio, in fact I had to turn it down quite a bit, and the best part is that I could listen to my music while flying. Not very satisfying with a normal headset. I however was not a fan of the mic. I put an Oregon Areo mic cover on it and it helped a lot, but the "boom for the mic was as limp as 30 day old celery. I finally taped it to some alum wire to give it a bit of a spine. Other wise I had to hold it in front of my mouth if I wanted to talk to some one. My cockpit is just a cover (factory wrap around) over the area that I sit. If I turned my head it would crack the squelch and I would get a shot of full motor noise. So it was necessary to turn up the squelch a lot to keep it from cracking. You asked about seal, and I did have a good seal, but you also pick up ambient noise through the bones that surround your ear as well. While I could hear great, I felt that the noise of that HKS was still too loud. I was considering using a set of ear muffs to help with the noise. To be clear- I never had any problem with hearing the radio or my music. My wife however often mentioned the motor noise was quite loud, and there was occasional static. ( I think that there are better mic's out there than the one that they use.) I have a base station here at the house so I can talk with the wife to get her input on clarity on her end of the conversation. I decided to try adding the ear buds to my Sig S45's. I have found them to be the best option for me even over ANR headsets. ( The ANR is set for GA and works best on the 2400 RPM's of those engines. Ours turning 6000 RPM, are out of the range that they generally work best at.) However wearing glasses I was not happy with the noise even with gel ear seals on the S 45's. I felt that I had to turn the sounds that I wanted to hear up to the point that my old experienced ears would be still getting damaging noise levels. I could not hear my music very well and if I played it as loud as I needed to hear it at all in the plane, it would cause me to wince at that level out of the plane. After completing the modification I rolled the plane out for some touch and go's. I plugged the ear buds in, covered my ears with the headset, and found that I had to turn the volume down on both the headset and the music radio for the first time. The noise level was substantially reduced from both the Halo set and the S45 before modification, with the ear buds. Upon landing my wife also confirmed that on her end the transmissions were a lot clearer, louder and without static. I will be using my Halo set as a backup. There was that much improvement. Thanks Malcom.

He's 'local' for me, and I bought mine by walking into his office. Nice guy & would probably work with you on the issues. Charlie, I really do not have any substantial complaint about the Halo headset. Yeah the wimpy mike boom is a bother, but not a real complaint. I feel that in the normal course of things it is something that the manufacturer would clean up in due time, but not enough of a problem to be a deal breaker. The reason that I am using the S45 with ear buds is just that it is better, and quieter. If I was flying a C150, I would use the Halo. In my operation however, it just isn't the best one.
